Summary of "Boron ink assisted in-situ boron nitride coatings for anti-oxidation and anti-corrosion applications."

Graphene, as a coating material, which shows high impermeability as an excellent barrier in oxidation and corrosion protection, has been reported to be less stable at elevated temperature. Meanwhile, sometimes the formed galvanic cell between graphene and protective surface will even increase corrosion speed. In comparison, boron nitride (BN), which shows the same impermeability with graphene, is believed to be a better coating material with its superior thermal and chemical inertness. In this study, an in-situ synthesis of BN coatings, grown by boron-ink, on both carbon and Cu for anti-oxidation and anti-corrosion purposes has been demonstrated. The thermogravimetric analysis and electrochemical analysis reveal that the BN coatings can effectively prevent the carbon at high temperature in air, and adequately slow down the corrosion of Cu in sodium chloride solution. These results indicate that boron-ink assisted in-situ BN coating has a high potential in the applications of oxidation and corrosion protections.
